Mini Cooper Forums - Mini Cooper Enthusiast Forums - Puzzler for the Tech Gurus! plug disconnected by intake

Dear forum:

I've searched and not found.. so if its been answered, please forgive.

I'm replacing a blown head gasket on my 2013 Mini. Or so I hope. Blew out the freeze/core plug between the oil galleries and the coolant system. The rest was a mess. I'm guessing the plug blew because combustion pressure got in the oil system and hence the blown head gasket. Everything looks clean inside so that's my hope. We'll see when it gets back together.

My puzzler.... attached to the intake plenum bracket is a bit of the wiring harness with two plugs. One goes to a breather hose valve of some sort, but the other wasn't connected to anything. The plug is a two conductor small plug, and the wires are orange and white. I can't find anything nearby that it could plug into. Does anybody know? or is this for an accessory I don't have? plug seems a bit dirty inside, but not 100,000miles dirty.

Your wisdom will be appreciated!
